Transforming Graphs

Which is a stretch?

• f(9x)

• f(x+9)

• f(-x)

• f(x+1)

The red graph is y=x².  What is the equation of the blue graph?

• y=(x-2)²

• y=(x+2)²

• y=x⁴

• something else

If the red graph is f(x) what could the blue graph be?

• f(x-3)

• f(4x)

• f(x)

• something else

The red graph is f(x).  What could the blue graph be?

• f(3x)

• f(x)+1

• f(x-3)+1

• f(x+3)+1

The red graph is f(x).
Which graph is f(-x)?

• Orange

• Red

• Blue

• Green

This is the graph of f(x).
If we drew f(x-2)+3 then where would the black blob move to?

• Stay the same

• Up 3

• To (2,4)

• To (-2,4)

• up 3 units

• down 3 units

• 3 units in the negative x direction (left)

• 3 units in the positive x direction (right)

If the blue is f(x)=x^2, the red must be

• g(x)=(x+3)²

• g(x)=(x-3)²

• g(x)=x²+3

• g(x)=x²-2

If the blue is f(x)=x^2, then the red must be

• g(x)=x²-5

• g(x)=x²+5

• g(x)=(x-5)²

• g(x)=(x+5)²

• up 2 units

• down 2 units

• 2 units in the negative x direction (left)

• 2 units in the positive x direction (right)
